[PATCH v2 0/9] emacs: Unify common key bindings and lots more

This is v2 of id:1377793557-28878-1-git-send-email-amdragon at mit.edu.
This fixes a problem found by Jani where notmuch-hello would reset
point placement when refreshing in Emacs 24.  It also inverts the
sense of notmuch-hello-auto-refresh and makes it a defcustom
(originally I'd intended notmuch-hello-inhibit-auto-refresh for
internal use only, but both Mark and Jani expressed interest in
setting it).

The diff from v1 follows
